LINING FOR GRAIN-SPOUTS.

SPECIFICATION forming part of Letters Patent No. 460,489, dated September 29, 1891.

Application filed J nne 1, 1 8 91.

To all whom it may concern.-

Be it known that I, LEROY R. TOPP, a citizen of the United States, residing at Louisville, in the county of J elferson and State of Kentucky, haveinvented certain new and useful Improvements in'Lining for Grain-spouts; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of spouts which are placed in slanting positions to permit grain to slide through them, to convey the grain by gravity from one receptacle to another; and the object of the invention is to provide a metallic lining in sections for such spouts, in order that any sections which ma y become worn in service may be removed and replaced by another with as little delay to the service of the spout as possible.

To this end my invention consists in a lining for grain-spouts, hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure I is a front view of a portion of a grain-spout, showing my lining ready for service. Fig. II is a longitudinal vertical section at the line ocof Fig. I. Fig. IIIis a transverse section at the juncture of two sections of lining-as, for instance, at y, Fig. I. Fig. IV is a vertical section longitudinal with the trough, showing a trough having a curved bottom, also showing a modification of my invention, which in this instance has sides as well as bottom.

10 represents a single section of my spoutlining; and it consists of a plate of metal 11, provided at the end with projecting studs 12, which I callhooks, and provided at the other end with holes 13, adapted to register with and to receive the studs of another similar plate. I prefer to make each stud with a slight rearward projection 14, adapted to pass under the adjacent plate to act as a hook, the more effectually to hold the stud in the plate. A series of plates of this style may be joined together to line a trough of any required length. It is evidently buta simple affair for any person with suitable tools to take out one Serial No. 394,660. (No model.)

of these sections and to replace it with another. The sections may be made of sheet metal of any kind, punched or stamped into the required form; but I prefer to make them by casting them in chillediron from patterns, as that grade of iron is both cheap and hard, making it peculiarly suitable for this work. In service this lining quickly becomes worn smooth, so that there is less friction upon it than upon wood, and the grain is less likely to become heated in sliding through a trough with one of my linings than in sliding through a wooden trough. It may sometimes become advantageous to form these sections with sides 15, as shown in Fig. IV, whereby a series of sections hung together as described form a complete trough, whether otherwise supported or not. Fig. IV also shows the sections with the plate of each made in curved form, suitable for a trough-bottom, longitudinally curved.

A trough made of tin or other sheet metal with the parts of it lapped one over another and joined permanently together, as with solder or other fixed joints, would not be myinvention, because the parts could not be sepa-' rated without cutting or destroying the joints, and parts permanently joined together would not be interchangeable. Spouts thus lined with metal made in interchangeable sections might be used as conveyors for cement, coal, and various other things besides grain.

Having thus fully described my invention, what'I believe to be new, and desire to secure by Letters Patent, is the following;

A spout-lining consisting of a series of me tallic plates, each plate being provided with studs at one end and with holes at the other end fitted to register with and to receive the studs of other similar plates, and the said studs having each a projection at one side, whereby the same may serve ashooks and be removable from the said holes, substantially as described.

In testimony \vhereofI affix my signature in presence of two witnesses.
